Red Rocks Amphitheatre will institute a new ticket policy for their 2018 concert season in an effort to fight scalpers.

The Denver Post reports that beginning with the new season, those tickets purchased in the first four rows of the venue must be used by their original purchaser. Those tickets will only be available via Flash Seats, an app owned by AEG Presents’ ticketing company AXS.

The venue also noted that eventually the entire venue will be ticketed with FlashSeats to make it easier to track tickets and restrict ticket transfers.

The famed Morrison, CO venue already has a few shows on the books for 2018 including Brandi Carlile, 311, X Ambassadors and others.
